When I turned on ADE on Friday, it suddenly couldn't find my Sony.

My laptop finds it, Calibre finds it, but not ADE. I have no idea what happened. ADE works fine, except for the detail that my Sony just don't show up.
I did perform a defragmentation of the harddrive recently, but that shouldn't cause any problems.
Main problem is that I am going to Barcelona tomorrow, and had planned to read them on the airport. sigh.
The irony is that I decided to uninstall Sony Library two weeks ago, since I felt that it was unnecessary

I suppose I'll have to reinstall it.
Edit: I re-installed the Sony software, and suddenly ADE can find my reader again. A necessary file must have been deleted when I uninstalled the Sony software....
